It really doesn't matter whether you go with an internal module or a USB dongle. The dongle is probably easier though . Both should work for tethering the XV6700 to your notebook for wireless data. Since the 6700 doesn't have Bluetooth 2.0 +EDR, the Bluetooth connection will be the bottleneck. If you're fortunate enough to be in an area that gets better than 500kbps throughput on EVDO, a USB cable would actually be the fastest.
